Energy is not required for passive transport.
No. Diffusion (passive transport) can take place without a cell. For example, if you were to put some coloured food dye into a cup of water, the food dye would spread until it eventually was a uniform colour. This is the process of diffusion, which is the movement of a substance down a concentration gradient. Passive Transport means no energy is required.
Active transport requires energy input to move molecules against their concentration gradient, while passive transport moves molecules along their concentration gradient without energy input. Active transport is typically carried out by transport proteins, such as pumps, while passive transport can occur through simple diffusion or facilitated diffusion.
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Absolutely, in order for passive transport to occur, the concentration on one side of the membrane must be larger than the concentration on the other side of the membrane. The molecules move from higher to lower concentration.

Diffusion is a form of passive transport, so nothing is required for it to occur.
this is known as "passive transport"
Passive transport is called passive because it doesn't require chemical energy intervention to occur. The four main types of passive transport are diffusion, facilitated diffusion, osmosis, and filtration.
Passive transport requires no cellular energy as it relies on the movement of molecules down their concentration gradient, such as diffusion and osmosis. These processes occur spontaneously to maintain equilibrium within the cell.
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.

Absolutely, in order for passive transport to occur, the concentration on one side of the membrane must be larger than the concentration on the other side of the membrane. The molecules move from higher to lower concentration.
Molecules move by passive transport down their concentration gradient, from an area of higher concentration to an area of lower concentration, without the input of energy. This can occur through simple diffusion, facilitated diffusion, or osmosis, depending on the properties of the molecules and the cellular environment.
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.Active transport requires energy, but passive transport requires none.Active transport requires a special protein to make the transport occur, but passive transport requires none.
